nection with the needle bar of the machine and with the slidable punch holder whereby the latter is normally pressed downwardand caused to move with the needle bar as thel latter is reciprocated, aprojecting part on the punch holder, acam lever and link mechanism-,operated thereby and a trip operated by the lever and link mechanism and adapted when put into action thereby to intercept the descent of the punch holder atl the required times and to hold the punch out of action.

2. The combination with a hemstitch sewing machine of a punch, a punch holder slidably supported on the needle bar of the machine, spring means in connection with -the needle bar of the machine and with the slidable punch holder whereby the latter is nor mally pressed downward and caused to move with the needle bar as the latter is reciprocated, a projecting part on the punch holder, a link slidably supported in the machine head, a vtrip adjustably supported on the link, a lever pivotally connected at one end to the other end of the link and itself pivn otally supported on the machine framing, a needle bar vibrating cam on which the other end of the lever rests and which is provided with a projecting portion adapted when the lever end engages it to move the lever and link 'and the Vtrip connected therewith so Copies of this patent may be obtained for five cents each, by addressing the"Gommissioner of Ttents; t

thatthe latter is moved out of the way of the projecting part of the punch holder, thereby allowing' the .descent of the punch holder during such times as the lever end is incontact with the projecting portion of the periphery of the cam, and spring inea-ns for maintaining the lever end in contact with the periphery of the cam.

3. The combination with a hemstitch sewing machine of a hollow needle bar, a punch, a punch holder slidably supported on the needle bar of the machine, a spring accom-` modated inthe interior of the needle bar `and bearing at its lower end on the sl'tlable punch holder whereby the lat-ter is normally pressed downward and caused to movewith the needlebar as the latter is reciprocated,"

a projecting part on the punch holder, a cam lever and link mechanism operated thereby and a trip operated by the lever and link mechanism `and, adapted when `put into action thereby to intercept the descent `of the punch holdervatthe required `times yand to hold the punch out of action.` i
